Thruster specs
Sleipner SRLP130 PRO: specs, price and the boats it fits
The SRLP130 is the largest 12 V retractable in Sleipner’s brushed line: twin propellers in a 250 mm unit give up to 353 lb of push for boats of about 43 to 62 ft, with speed control from the joystick. Sleipner says it deploys and retracts quickly, with the motor fixed to the moving casing.
Not sold in the US right now. No US store or distributor lists the Sleipner SRLP130 PRO: we checked Imtra’s US catalog (the Sleipner distributor), Defender and Fisheries Supply on October 15, 2026. Its specs and parts stay here for owners of boats built or bought abroad. For one to buy here, see the models on the Sleipner (Side-Power) review that have a US price.
Sleipner prints no price and no US dealer lists one; expect a quote. On 12 V the motor draws a very large current, so give it batteries of its own close by and short, heavy cable. Sleipner’s minimum battery figure for it is printed lower than for the same-size SE130, so check the battery with your installer. See the specs.
At half power or less it runs close to continuously; at full power keep each push within 2 to 3 minutes. The controller trims power as the motor warms rather than shutting it off. Two-year warranty, transferable to the next owner.
Fitting it yourself? The installer section has every spec, and the Sleipner (Side-Power) review sets this model against the rest of the Sleipner range.

How much of the install is yours
DIY levels
- Level 5: Owner install. No yard, no electrician.
- Level 4: You fit it, electrician connects. You mount and wire it; a marine electrician makes the final connections.
- Level 3: Split with the yard. The yard does the below-waterline part; you do the wiring.
- Level 2: Wiring prep only. The yard fits the unit and does the hull work; you do the wiring prep.
- Level 1: Yard job. A qualified professional does all of it.
You Yard Electrician. The bar is labor hours; a haul-out is a note.
How we rate DIYYou: 4 to 16 h Yard: 40 to 88 h Electrician: 2 to 4 h Plus a haul-out.
- Cut the hull and fit the housing and mechanism Yard 40 to 88 h Nobody publishes an hours figure. Fisheries Supply says installation is significantly more expensive than a tunnel, and that is too loose to turn into a number. So this is the tunnel’s own banded figure plus a quarter, which keeps it above a tunnel as the distributors describe it.
- Mount the battery box, switch and fuse holder; run and secure the cables You 4 to 16 h Our estimate. No maker times this step, and a first-time owner is slower than a yard, so the range is wide.
- Final connections at the battery and the motor, load test Electrician 2 to 4 h Our estimate. Nobody publishes a time for the final connections and test on their own.
Your part needs:Heavy battery cableCrimping big lugs
A qualified marine electrician should make the final connections and test them before first use. Hours are labor only.
Is it right for your boat?
Our figure is the longest boat one unit can steer in a 15 knot wind. It is a range because each kind of boat catches the wind differently. Here a houseboat gets full thrust to 47 ft, and a catamaran to 68 ft. The maker gives one range for every boat.
The table below tries the Sleipner SRLP130 PRO on each kind of boat, at every length that kind of boat is built in. The wind is 15 knots and the rules are the finder’s own. A length counts as a fit when the unit gives the thrust that boat needs at the bow and the maker lists it for that length.
A boat up to 10 percent past the maker’s range still counts here, as it does in the finder. So the table runs down to 39 ft and up to 68 ft, just past Sleipner’s own range (43 to 62 ft).
| Boat | Full thrust at 15 knots | Still a fit, in lighter wind |
|---|---|---|
| Pontoon & tritoon | Not listed. A retractable drops down inside the hull, and a pontoon has no hull depth to drop into. | |
| Sailboat | 53 to 63 ft | 64 to 68 ftfull thrust to about 14 knots at 68 ft |
| Houseboat | 39 to 47 ft | 48 to 68 ftfull thrust to about 10 knots at 68 ft |
| Catamaran | 60 to 68 ft | None |
| Trawler | 52 to 62 ft | 63 to 68 ftfull thrust to about 14 knots at 68 ft |
| Motor yacht | 52 to 62 ft | 63 to 68 ftfull thrust to about 14 knots at 68 ft |
| Bass & flats | Not listed. A retractable needs hull depth to drop into, and these planing hulls have almost none forward. | |
| Wake & ski boats | Not listed. A retractable needs hull depth to drop into, and these planing hulls have almost none forward. | |
| Express cruiser | No length. More thrust than the boat needs. | |
| Center console | No length. More thrust than the boat needs. | |
Reading the two length columns. The first column is where one unit gives all the thrust the boat needs in 15 knots. The second is where the finder still lists it: the unit falls short of what the boat needs by no more than 10 percent, and gives the whole figure only in the lighter wind named. On a boat shorter than the first column’s shortest length, the unit is more than the boat needs.
It is sized for five kinds of boat here. For your own boat, the finder gives an answer that also counts your drive and who does the fitting. The compare page sets this unit beside others.
What it costs fitted
No US dollar price is published for the Sleipner SRLP130 PRO, so we build no total for it. The yard’s share of the job is on the cost page.
The sizing and the costs on this page are estimates, for guidance only and without warranty. They are no quote, and nobody has inspected your boat. Check them against the maker’s manual and your yard before you rely on them. Terms of use.
What else you buy
What follows comes from Sleipner’s SE80 to SE150 installation guide, document 2687 rev 30, 2025, read 30 September 2026. That manual is written for the tunnel units. A retractable unit brings its own housing, so there is no tunnel to buy.
- In the box
- The gasket, bolts and anode come with the unit. The SEP guides call the power controller "the included PPC unit".
- Bought separately
- The ANL fuse and a main switch ("must include"), the control panel with its own guide, the panel cable and the battery cable.
- Charging
- The word "charging" is not in any of the Sleipner guides we read. The battery is sized by cold cranking amps, and a battery near the thruster is suggested. How it gets charged is left to you and your installer.
The manual’s words, page 19: “For installations on large vessels with bow and stern thrusters or catamarans a dedicated battery for each thruster should be considered.”
A yard job adds these parts on top of the unit: $336 to $815 for the priced ones below, at Fisheries Supply’s prices on 30 September 2026, plus the batteries, cable and charger.

Draw, cable, fuse and battery, at each voltage
These are the maker’s own figures, at each voltage it is sold at. The cable is the size for the shortest run in the maker’s table. A longer run may need heavier cable, and the wiring calculator works that out for your own boat.
| Voltage | Draw | Maker’s cable | Fuse | Battery | Run limit |

What holds up and what to weigh
Each point names the fact it rests on.
What holds up
- Sleipner sells it for either end, so it can go at the bow or the stern.The maker's listing
- It is sold at 12 V and at 24 V.The maker's and dealers' listings
- Sleipner also prints a second, lower thrust figure for when the battery sags under load: 287 lb at 10.5 V.The maker's published rating
What to weigh
- The boat comes out of the water to fit it: it needs a large hull opening below the waterline.The mounting: a bore through the hull, or a housing recessed into it
- No US dollar price is published for it, so we can work out no fitted cost.The maker and the dealers the database reads
What the manual and listings say
This is the note we keep on the Sleipner SRLP130 PRO, written from the maker’s manual, its product pages and the dealer’s listing.
In the box: Proportional: the joystick sets how hard it pushes. The power controller (PPC) is included.
12 V
This retractable lives in a housing let into the hull through a large opening, and drops when used. It is a bigger yard job than a tunnel. It also has a mechanism to keep in order. PRO means proportional: the joystick sets how hard it pushes. The 2026 catalog says to expect close to continuous run time at half power or less.
This is the largest 12 V retractable in the brushed line, 250 mm, for boats of 43 to 62 ft. It is rated 160 kg at 12 V and 130 at 10.5. The page rates the brushed motor for two to three minutes' running at 20 C. The control panel switches itself off after about six minutes unused. There is no dealer price, and the maker publishes none.
24 V
The 24 V build of the SRLP130, with speed control.
Videos
Two of Sleipner’s own videos, from its YouTube channel: how the SRV and SRL retractables go in, and X-Yachts on the ERV100 retractable in a 47 ft sailboat. They are the maker’s pitch. Watch them for what the unit looks like and how it goes in, and take any claim back to the figures above.
Other sizes and close alternatives
Sleipner also sells this thrust built another way. Each has its own page:
- Same thrust: Sleipner SRV130, $22,730.
- Same thrust: Sleipner SRL130.
These are Sleipner’s nearest sizes by thrust, in any of its lines.
- One size down: Sleipner SRLP100 PRO, 256 lb.
- One size up: Sleipner ERV170 eVision, 375 lb, $26,455.
These are other makers’ units of the same style, for the same end, within a quarter of its published thrust. Each is that maker’s nearest match.
- Lewmar 250VRTT Vertical Retractable, 353 lb, $29,417.
Every model with a page here is listed, maker by maker, on the thruster index.
